Txl North Unit #964 (API 42-135-39147) is a well in Ector County operated by Formentera Operations LLC, completed September 4, 2007 and listed as shut in on the RRC schedule, shut in January 1, 2017.

The RRC has issued one drilling permit, issued July 13, 2006, permitted to 6,460 ft.

It was permitted by Anadarko Petroleum Corporation and has since transferred to Formentera Operations LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Glorieta, Clear Fork, Tubb.

Its lease has reported 13.9M barrels of oil and 40.3M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 496 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
